While you may not get the same rate of failure as with spinning disks, drives do fail and the ability to shift seemlessly from one drive to another automatically when using raid 1 far outweighs any disadvantages (which is basically just double the cost for storage devices). I would always use raid 1 on important devices. -------------- next part -------------- A non-text attachment was scrubbed...
